I thank you for the advice, but I cant think of a way to heat the center. In my Proton laser, I had the Protons pass through controled WALL, but photons wont do that
oh I didn't see the INVS my bad. I guess it's invisible. Still it has trouble heating close to the middle
check the beam in heat view, it starts hot but then only the edges are hot after. there's nothing to transfer heat to the middle of the beam
